WINDING-MACHINE.

Specification of Letters Patent. Patgnted Aug. 11%, 1911?.

Application filed December 28, 1914. Serial No. 878,765.

To all whom it may concern:

Be it known that I, WILLIAM MARO'ROFT, a citizen of the United States, residing at Cranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Winding-Machines,' of which the following is a,

' the cop or quill to be wound with tapered or conical ends. A further object of my improvement is to provide a traverse-shortening mechanism which can be applied to standard types of machines now in general use without requiring any material alteration in the structure or arrangement of the I basic machine.

Fig. 4 is an enlarged elevation of the thread-guide and its connected parts;

Fig. 5 is an enlarged, perspective view of a part of the guide-mounting through which glue thread-guide is connected to the traverse- Fig. 6 is a similar view of another part of the guide-mounting; and

Fig. 7 illustrates the type of cop or quill wound on machines fitted with my improved mechanism.

Referring to Fig. 1, the basic or main machine, as here shown, is of a. well known type substantially like that described and illustrated in United States Patent No. 589.587, granted to S. W. 'Wardwell, Sept. 7 1897, and widely used for winding shuttle cops or quills by the Universal or V-wind system. It consists essentially of a rectangular frame A having parallel uprights a, a formed with bearings for the horizontal winding-spindle B and cam-shaft C. The spindle B is driven through the medium of a driving-pulley 6 adapted to be rotated from a suitable belt, not here shown, which can be shifted onto the loose pulley b when it is desired to arrest the operation of the machine. The spindle B also carries a pulley b which is connected by a belt 6 to a pulley b on a shaft D. The shaft D is mounted to rotate in bearings on a frame d which is pivoted at d, d on the cam-shaft C. At the left-hand end the shaft D carries a pinion d which meshes with a gear 0 on the cam-shaft C. The pulley b is preferably of the expansible type commonly used on winding machines of this kind and can be adjusted to Vary the diameter of its rim by simply turning the hand-nut 6 Through 7 this adjustment theratio of speedvbetween the spindle B and the cam-shaft C can be varied to regulate the laying of the yarn or thread by the reciprocating thread-guide in a manner well known to those versed in the art.

The cam C is mounted fast on the shaft C and is driven thereby, through the connections above described, to impart reciprocation to a horizontal traverse-bar E. Thea bar E is arranged parallel with the winding-spindle B and is mounted to slide 1ongitudinally in bearings a, a of the frame A. The bar E is preferably arranged to project from both sides of the frame A to adapt it to carry one or more thread-guides G at either end so that the machine can be arranged to wind a plurality of quills at F extending parallel with the rod E. On

the outer endof the rod F is supported a bracket H which carries an end-bearing h for the cop-tube 2, see Fig. 2. The enda key or spline I) on the spindle to rotate the tube. The bushing h is retractable in the bracket H to allow the insertion and removal of the tube 2 as usually provided for in machines of this type.

The thread-guide G is mounted on the traverse-bar E through the means of an arm or holden G arranged to swing about the axis of the bar to allow the guide to move outward away from the surface of the coptube as the yarn is built up. thereon. Re-

ferring to Fig. 1, the traverse-bar E is reciprocated from the cam C through the engagement of the groove 0 in the latter with a roll 71 carried by a cross-head I attached tothe bar.

Heretofore it has been the common practice to reciprocate the thread-guide with a constant length of traverse throughout the winding of the cop or quill. This results in building up the ends of the quill with a flat formation; that is, the ends will be square with the axis of the quill. In winding certain varieties of thread, such as hard,

glossy silk and other like materials, it has been found very diflicult to build the quills with perfect ends while employing this style of winding. Owing to theslippery quality of the thread the coils of winding are liable to slide off the ends of the quill and fall down on to the tube, thereby causing a malformed package from which the yarn cannot be unwound without snarling and breaking. To obviate this defect in the quills it has before beenproposed to wind them with tapered or' conical ends as illustrated particularly in Fig. 7 but in most cases it has required special machines built particularly for winding in the manner described to produce taper-ended quills 'of the form shown. My new improvement makes it possible to adapt a usual type of quill-winder for this style of winding and the manner of carrying out the-improvement will next be described;

It will be-observed from the foregoing explanation that the traverse-bar -'E is reciprocated from the cam C .With a constant extent of traverse throughout th whole operation of the machine. As usually provided in machines of this type the threadguide G has a fixed relation to the traversebar, that is, longitudinally thereof, and hence the guide will be given a constant extent of traverse throughout the complete winding operation for each cop. In my present improvement I maintain the reciprocation of .the traverse-bar constant, so as memes not to require any alteration in the main traversing-mechanism, but by providing means for periodically oscillating the guide in a plane parallel with the bar I effect the desired gradual shortening of traverse of the guide from start to finish of the winding. To adapt theguide G for this oscilla- V tory movementwith respect to the traverse bar E I pivot it on an axis crossing the line of movement of the bar as shown more par ticularly in Figs. 2 and 4. The guide G, as before described, comprises an arm or guide holder G which, as shown in Fig. 4, embraces the button or element 9 provided with a notch 9 through which the yarn passes. Secured to the guide-arm G in line with the notch g is a guide-eye g illus trated in Fig. 2, but omitted in the other views for the sake of clearness. The midportion of the guide-holder or arm G is formed in somewhat of a banjo shape continued in the downwardly extending arm 9 provided with a suitable hole through which the pivot-stud 9 passes. screwed into the depending arm or lug g of a'supporting-member or sleeve g", shown in detail in Fig. 6, which is adapted to sur-- round the traverse-bar E and free to turn thereon. Preferably, the stud g is shouldered to adapt it to be set up against the face of the lug g so that the arm G will be allowed free play to oscillate about the axis of the stud. The sleeve 9 while free to turn on the traverse-bar E is held longitudinally thereof by means of a second bifurcated sleeve or bearing J shown in detail in Fig. 5. The sleeve J is preferably constructed of sheet-metal bent to form two spaced-apart, ring-like bearings j, y connected by a cross-piece or brace j. The bearings j, y do not completely'encircle the bar E, but are formed with laterally-projecting, bent-over ears j adapted to be clamped to the cross-piece j by means of the screws 5' Through this means the bearings j, j are caused to bind on the rod E to secure the member J in position. As before stated the guide-arm sleeve 9 is located on the bar or rod E between the bearings y, j. A flat, steel spring K is secured to the cross-piece j of the member J by means of the screws 9' see Fig. 3, and 13 formed with a tail-piece k which reaches down to bear on the surface of the sleeve g Through this arrangement a slight friction is applied on the sleeve 9 to resist its turning movement on the bar E, thereby tending to hold the guide-arm G in whatever position it may be adjusted. Projecting upwardlyfrom the cross-piece y" of the member J is an arm or finger j on which is p1voted an L-shaped member L. Preferably,

the member L is pivoted on a headed stud Z riveted through 'the arm Riveted through the upright arm of the. member 130 The stud g is L'is a bar or rod M which for the sake of convenience I term the radius-rod. The rod M passes through an elongated slot at in a swiveled bearing-member N mounted on the guide-arm G, see Fig. 4. Preferably the member N is cylindrical in shape adjustable rod P held in a clamp-member R.

The end of the rod P is flatted off at p and provided with a lateral hole in which the reduced shank 0 of the member 0 is free to turn. The projecting end of the shank 0 is reduced in diameter at 0 and riveted through a washer 0 which serves to hold the member 0 in place while allowin it to turn on the rod P. The clamp-member R- is formed to straddle a rod S which extends in a horizontal direction in front of and parallel with the winding-spindle B, see Figs. 1 and 2. The rod S is supported in bearings at the ends of two arms 6, t which form part of a bracket or frame T secured to the top of the main frame A of the machine by means of the screws 25', t. Suitable set-screws s, s are screwed into the bear-.

ings on the arms t, t and tightened against the rod S to hold it in position. In Fig. 1 the projecting ends of the rod S are shown as partly broken away to prevent obscuring the other parts of the machine. As shown more particularly in Figs. 2 and 3, the clamp-member R is formed with two arms or lugs r, 1" provided with openings through which the rod P extends in position to lie across thetop of the rod S. Preferably, the rod P is flatted off on its under side at p, as shown in Fig. 1, and the rod S is also flatted off at s to form more extended bearing surfaces where the rods cross each other. The flat portion 8 on the rod- S is arranged at an angle to the horizontal so that the rod P and radius-rod M incline downwardly to a point just above the traverse-bar E, see Fig. 2. A set-screw r is screwed through the clamp-member R with its end bearing against the rod S and through this means the rod P can be clamped against the flatted surface of the rod S to hold it'firmly in place. By loosening the set-screw r the clamp R can be adjusted longitudinally of the rod S and the rod P can be adjusted longitudinally of its bearings 1', r so as to regulate the position of the member 0 which serves as a pivot for the radius-rod M.

It will be understood from the foregoing explanation that when a usual type of wind ing machine such as herein first described is to be fitted for winding taper-ended quills of the form shown in Fig. 7, certain parts are added to the basic or main machine. That is to say, the regular type of threadguide ordinarily used on the machine is replaced by the one here shown which is at-' tached to the standard traverse-bar E as described. The bracket T is fastened to the frame A by the screws t which fit tapped holes already provided in the standard machine. The rod S is next adjusted in the bracket R and the mechanism carried thereby is set in place and connected with the guide G. After the parts have been properly correlated and adjusted the machine is ready for use and operates as follows:

The cop-tube z is placed in position by seating one of its ends on the end of the Winding-spindle B and its opposite end on the spindlebearing h. It is here called to attention that instead of winding the cops 'or quills on the wooden tubes 2, as shown,

they might be wound on paper shells or tubes as sometimes provided. For instance,

where more than one quill is to be wound 'on each end of the winding-spindle the main spindle B is extended to the proper length to accommodate as many paper cop-tubes as desired. .For the sake ofclearness the operation of one thread-guide only will be'here described and that in connection with the arrangement illustrated in the drawings. As here arranged the guide G is first adjusted with the rounded face of its button 9 bearing against the surface of the cop-tube 2 and the thread or yarn is led down from its source of supply, generally arranged above, but not here shown, and threaded through the eye 9 and notch 9, see Fig. 1. The free end of the yarn y is then attached to the tube 2:, and the machine is ready to s be started. This is accomplished by shifting the driving-belt onto the fast pulley b, when the spindle B will rotate the tube a and, through its connections with the camshaft C, will drive the cam C to reciprocate the traverse-bar E. As the bar E slides back and forth in its bearings a, a the guide G, held longitudinally thereon by the member J, is carried with it and the thread passing through the guide-notch will be laid on the tube a in open helices to build up crosswound layers in the manner well known to those versed in the art. As the guide G traverses back and forth parallel with the axis of the winding-spindle the member J, mounted on the bar E, will carry the end of the radius-rod M to which it is attached back and forth with an oscillating movement as illustrated by the dash-lines in Fig. 3. During this swinging movement of the rod M its supporting member L turns on the pivot Zwhile at'its opposite end the swiveled member 0 allows both a pivotal and sliding movement of the rod. The member N also swings on its pivot as the guide moves back and forth to accommodate itself to the oscillation of the rod. M. Now, as the yarn builds up on the tube a it forces the guide G away from the axis of the winding-spindle in a well-known manner, this movement being provided for by the turning ofthe guidesupporting member 9 on the rod E. At the beginning of the winding, when the threadguide G is bearing against the tube a, the

1g guide-arm G will stand substantially at right-angles to the radius-rod M, that is, viewing the parts as shown in Fig. 2. Under these conditions the arm G will also remain in substantially perpendicular relation to the traverse-bar E, viewing the parts as shown in Fig. 4, throughout the whole extent of its traverse. In other words, at the commencement of the winding the threadguide arm G will remain in fixed relation'to the bar E and hence the guide-button 9 will have an extent of traverse equal to the whole length of traverse of the bar. When, however, the guide-arm G begins to swing outwardly away from the axis of the tube e,

5 due to the growth of the winding, its controlling-member N will slide along the radius-rod M toward the axis of oscillation of the latter, and this will have the eifect'of changing the longitudinal position of the '30 thread-guide with respect to the bar E.

That is to say, as the controlling-member N slides toward the pivot-point of the radiusrod M, it will cause the guide-arm G to be displaced longitudinally of the axis of the bar E at the extremes of travel of the latter. In other words, the guide-arm G will be caused to rock inwardly at the extremes of traverse of the bar E, as shown in Fig. 1, so that the effective length of traverse of the A0 guide G at its point of delivery, '5. 6., the notch g of the button will be gradually shortened. Stated briefly, the guide-arm G, influenced by the growth of the winding, slides back on the radius-rod M and the angular position of the rod at each end of the traverse of the bar E acts to tilt the guide-arm away from the ends of the cop so that the yarn will be wound with progressively shortened layers to build up a cop or 6 quill with tapered ends.

By adjusting the rod P longitudinally in its bearings the relation of the pivot of the radius-rod M to the guide-arm G can be varied so that angular movement of the rod is altered to give a greater or less extent of oscillation to the guide G on the bar E; and in this way the degree of alteration in the length of layers of the winding can be regulated as required. By regulating the 60, change in the length of traverse of the guide in this manner the amount of taper at the ends of the cop can be controlled according to the form required for'difi'erent classes of material. Through this adjustment 1t 1s also possible to adapt the machine for difaaseaea ferent lengths of cops in accordance with the particular length of throw of the cam C being used on the machine.

I am aware that it is not new in the art to wind quills or cops with conical or 7 tapered ends. I am also aware that it has before been proposed to pivotally mount the thread-guide on the traverse-bar to provide for an oscillating movement thereof in addition to its main, straight-line traversemotion with the bar. The object of my present improvement is to provide a device of this sort which can be readily applied to machines now generally in use without requiring machine work or special fitting of so the main elements of the winding mechanism. In my previous application for U. S. Patent, Serial 780,27 5, filed July 21, 1913, I have disclosed an invention having the same object in View, but in the present improvement I accomplish the purpose with a more simple and compact mechanism, capable of a wider range of adjustment, and adapted to be manufactured at a much less cost.
